CRANK DRIVING MECHANISM Eon AnDING-NIACiI-INEs.

To. all whom it may concern:

Be it known that I, HENRY KI'iNTzLER, a

'citizen of the United-States, and resident of Kingston, 'Luzerne county, Pennsylvania have invented certain new and useful Improvements 1n Crank Driving Mechanism for Adding-Machines, of which the followin is a specification.

,- Iy invention relates to a locking mechanism for motor actuating devices for adding machines.

In the following specification the invention is shown and described as applied to the Wales adding machine and to a peculiar driving mechanism attached thereto, but it will be'understood that it is equally applicable to other forms of driving mechanism and power transmitting devices, or other adding machines. The power transmitting mechanism referred to is described and claimed in Letters Patent of the United States No. 902,103, issued Oct. 28, 1908, to Charles N. McFarland, and, in brief, comprises a continuously rotating drum actuated by a motor, a counter or intermediate shaft on which the drum is loosely mounted to revolve, a carrier rigidly-mounted on the shaft, a control ring mounted to rotate on the'shaft and provided with projecting toes,

a driving armeccentrically mounted on the carrier, means for=placing a constant ten- 'sion on the driving arm, a holder adapted normally tokeep the driving arm out of contact with the revolving drum inside of which the carrier is mounted, and means for interrupting the function of such holder, comprising a depressible key or actuating bar and means also whereby the function of the holder may be automatically restored.

The purpose of this invention is to provide means for locking the actuating device of a the power transmitting mechanism and preventing its accidental movement before the 5 cycle of operations governed by it is com- Specification of Letters Patent.

an adding machine and 2 is a part of one of its SIdB fIHmBS of WhlCll there are two, one

.on each side of the machine; 8 is an operating rock shaft by the oscillation of which the mechanism of the adding machine is actuated. Secured'to this shaft 3 is a sector 1 havinga stop foot 5 to limit its movement in one direction. sector at 7 has a lower extension 8 provided with a slot 9 adapted to engage with a wrist pin 10- of a crank 11 secured to an intermediate shaft 105 moved from the power transmitting mechanism.

A link 6 pivoted to the Mounted ona pair of elbow levers 20 which move together is a depressible actuator bar 21 adapted to. move'vertically. The levers are adapted to swing on pivots 22', projecting from the frame 2 of-the machine. At their lower extremities they are coupled by a link 28 so that they will move together and to one of them at 24 is pivoted a link-25 which in turn is pivoted to a crank 26 rigidly secured to'a rock shaft27, to' the other end of which is secured a crank 28 which in. turn is pivoted to a vertically placed actuator link 29'pivoted on a crank 30 mounted on a rock shaft 31 which in turn connected to the device by which the function of the holder of' the power transmitting The power transmitting mechanism is the same as that described in the Patent No. 902,103, above referred to. 100 indicates the motor and 101 is a shaft moved therefrom and carrying a worm 102 in mesh with a worm gear 103 rigidly secured to a shell, 202 so thatthe gear and shell rotate on an intermediate shaft 105 on which they are loosely mounted.

The coupling mechanism comprises a control ring 113 provided with'projecting toes 114 and slots 121. It also comprises a holder consisting of an arm 151 adapted to engage the toes 114 and provided with an arm 153 having a restoring roller 154. A cam 113 is mountedwith the control ring which has depressions 113, oneof which is opposite roller 154 when the clutch is at rest, allowing the roller 154C and arm 153 to be moved inward to trip the clutch.

' nism, the arm 153 is cammed back to its original position.

To the shaft 105 is attached a spider 105 to which is pivoted at 105 a pair of friction shoes 105 adapted to engage the constantly rotating shell 202. Springs 105 attached to the spider and the shoes tend to effect this engagement, The shoes are kept from contact with the shell by means of the pin and slot connection 121 with the control ring 113. \Vhen the ring 1131s released at 11% the springs 105 contractandthe shoes move out 'ardly until they bear against the shell, which thereupon "communicates its motion to the shoes, l05",lspider 105, and shaft 105. I y

In the operation of th'e machine, after an item has been enumerated in the usual manner, the actuator bar 21 is depressed by the operator. This moves the link to oscillate the crank 26 and rock the shaft 27 which in turn lowers the crank 20 and actuator link 29 and rocks the shaft 31. This moves the arm 151 to the left, releases the toe 114 with which it has been engaged and permits the constantly rotating motor 100 to be coupled to the intermediate shaft 105 whereby the crank 11 is rotated in the direction indicated by the arrow. The wrist pin 10 therefore reciprocates the slotted link 6 whereby, through the sector 4, the shaft 3 is vibrated. By this time, the arm 153 has performed its function of disengaging the motor from the shaft 105 and, through the spring 50,the actuator bar 21 and its connections have been retracted to their original positions and the arm 151 is again restored to its position in the path of the too 11 None'of the parts above described constitute any part of the present invention. As before stated, this relates to allocking mechanism fOl'thQ motor actuator and provides ineans whereby the depression of the actuator bar (21) is prevented before the cycle of operations just described is completed.

The crank 26 is provided with an upwardly extending arm (200) having a slot 32 adapted to engage a pin 33 projecting from the frame of the machine and adapted to limit its movement. It also is provided with a laterally projecting flange 34. Loosely mounted to oscillate at a convenient point near the arm 26 and in the form'of the device shown surrounding the operative rock shaft 3 is a cooperating locking plate 35 provided with a projecting arm 36 hava lateral flange 37 adapted to cooperate with the flange 3% of the crank 26, anda second projecting arm 38 having an inwardly extending flange 39 adapted to be engaged by the stop foot 5. It is also provided with slot 40 adapted to engage a pin 41 pro jecting from the frame 2 of the machine.

5-1 spring 43 is adapted to move the arm 38 shaft 3 is oscillated the sector 4 is moved with it toward the left and its foot 5 moves away from the flange 30 of the plate 235 permitting the latter, under the influence of its spring &3, to be moved slightly until the pin 4-1 contacts with the end of the slot 10. This movement swings the flange 37 into the path of the flange 34: on the crank E20, as shown in Fig. 2, and locks the latter against any movement to the right and obviously, by preventing the movement of the crank 20, prevents any actuation of the aetuator bar 21, actuator linkQQ, or any of their intermediate mechanism. The flanges 37 and 3st remain in this locked position until toward the end of the rearward stroke of the shaft, the foot 5 contacts again with the flange 39 and depresses it to move the plate 35 and flange 37 to an unlocking position, at the same time rcstretching the spring 43.

The connection between the crank 11 mounted on the intermediate shaft 105 and the slotted link'G need not necessarily be through such a wrist pin and slot. Such connection is convenient to permit of a slipping movement between the motor and the main shaft but except for such convenience a direct pivot connection would be equally as useful and etlicient.
